פָּשֹׁ֤עַ וְכַחֵשׁ֙ בַּֽיהוָ֔ה וְנָס֖וֹג מֵאַחַ֣ר אֱלֹהֵ֑ינוּ דַּבֶּר־עֹ֣שֶׁק וְסָרָ֔ה הֹר֧וֹ וְהֹג֛וֹ מִלֵּ֖ב דִּבְרֵי־שָֽׁקֶר׃
Transgressing and denying the LORD, And turning away from following our God, Speaking oppression and perverseness, Conceiving and uttering from the heart words of falsehood.
Ibn Ezra on Isaiah
פׇּשֹׁעַ וְכַחֵשׁ In transgressing and lying. These are infinitives; the meaning of פשע is to renounce obedience.
Rashi on Isaiah
sprouting and giving forth Heb. הֹרוֹ וְהֹגוֹ to shoot and to give forth. הֹרוֹ is an expression of (Ex. 15:4) “He shot (יָרָה) into the sea.” (Another explanation: הֹרוֹ means: the teacher and the disciple, a gerund.) הֹגוֹ is an expression of (II Sam. 20:13) “When he was removed (הֹגָה) from the highway”; (Prov. 25:4) “Take away (הָגוֹ) the dross from the silver.”
